Application filed. May 12',

' My inventionrelates to'eleva'tors used in oil well apparatus and more particularly to It is a purpose of my invention to provide asucker rod elevator which can be engaged around the sucker rod by merely moving the same sidewise into position'witho'ut the manual actuation of any means to unlock the locking members provided thereon.

It is a further purpose of my invention to provide a device of the above mentioned character that is provided with a pair of pivotally mounted jaw members forholding the sucker rod in position, said jaw members being angular and; having portions that are normally arranged in converging relation so that movement of a sucker rod into the- .opening provided inthe body portionot the elevator through tlieppening in one side thereof which the normally close, will separate the jaws to permit the rod to pass to linal position in the elevator, and after said rod has passed to such position, the. jaws will move to closing position. The

jaws are preferably so mOunt-edthat afterthe" rod has reached its 'tinal jposition',"any tendency of the same to move outwardly relative tothe elevator will; cause the jaws to move-into firmer engagement with cache other, thus automatically preventing the separation of the jaws when therod tends to move out .ot'the elevator but permitting separation thereofiiwhen the rod is moved into position'in the elevator.

It is another purpose of my invention to provide angular, substantially L-shaped jaw members pivoted substantially at the junction of the legs of the jaws, oneleg of each jaw extending outwardly in diverging relation away from the pivot and being provided with resilient 'neans tor moving the other legs of the jawsinto engagement,

said other legs of the jaws being thenarranged in converging relation .to each other and extending inwardly from the pivots away from the open end of the passage leading into the body portion of the elevator.

Itis a further purpose of my invention to provide means for moving "the jaws against the action of the resilient means into releasing position, comprising an angular actuating member and means interposed;be-' tween the actuating member and thele'gsof the jaws having the resilient means in engagement therewith for moving said jaws against the action of the resilient means upon closed side thereof.

Fig. dis asection t Fig. 7 is a;

perspective view of one of the portion 10 which is provided with an opening 11 extending through the same from one end to the other end thereof, said opening extending substantially at right angles to' theaxis of the pivot llugslEZ provided for pivoting the bail member 13 .to the body portion 10. The body portion 10 is further-provided witha passage l l'fextending laterally from the opening .111, which is enlarged tocations'o l' parts as would occur to a person g o IS a similar view thereor with the ken substantially at right angles toFig. 4, and

ward the outer end'15 thereof to provide fol-the ready passageof the sucker rod through, the sanieinto the opening'll. The

openingll is provided'with a. curved wall portion 17 against which the rod 16 may seat. i

provide'the chambers l8jon opposite sides of the passage 14:,thus providing top and The body po 'rtion lOis hollowed out to" loo sides of the passage 14, said walls 19 and 20 i being provided with obliquely extending portions 22 and substantially parallel por tions 23 toudefine the assa e' l4; and the 1 I 1 t? H ill flaring mouth 1 5-thereof. Mount-ed between the walls 19 and 20 in the openings 18 are the aw members 24, said jaw members being mounted on the pivots which are mounted in the wall portions 19 and 20 and extend between the same. Said jaw members are substantially L-shaped with the pivot openings thereof located substantially at the angle of the L and are thus provided with inwardly extending leg portions 26 which normally converge inwardly from the pivots 25 .at an acute angle to each other so that the same engage to close the passage leading from theopening l1. The legs 26 of the j awe 24 are held in engagement by means of the compression springs 27 which engage in suitable recesses 28. provided in the wall portions 21 and in suitable recesses 30 provided in the legs 31 of the jaws 24, said legs diverging from each other away from the pivots 25 and away from the passage 14.

The corners of the jaws may be rounded at 32, 33 and 34, but are preferably slightly bevelled at 35 so as to provide engaging faces for thejaws when the same are in engagement with each other. p

Mounted in suitable passages. 36 provided in the portion 10, are the pins 37,, said pins engaging with the legs 31 of the jaws 24 at one end thereof and being engaged at the other end thereof by the arm 38 of the angular actuating member 39 which is pivotally mounted on the pivot member 40 extending between the laterally extending walls 41 on the body portion 10. Said actuating member 39 is provided with any suitable hand grip or handle portion 42 and if desired, the body portion 10 is provided with a ledge or flange 43 extending outwardly therefrom so that a grip can be obtained on the member 42 by engaging the hand with the ledge 43 and the handle portion 42, the handle portion 42 being moved downwardly when the hand grips both the portion 42 and the ledge 43. Any suitable grooves or other undulations or 45 may be provided on the members 42 and 43 for preventing slippage of the hand thereon. A coiled compression spring '46 surrounds each of the pins 37 and engages with the arm 38-01 the actuating member 39 so as to hold the same in an upright position, as shown in Fig. 6. The body portion 10 is provided with a projecting flange portion 47 which has a bevelled face 48 with which the correspondinglyIbevelled portion 49 adjacent the enlargement '50 on the sucker rod engages when the same is in position in'the elevator.

It will be obvious that if the rod member is moved relative to the elevator towardthe opening 11 from the entrance to the passage 14, thesa me will cause the aw-s 26 to yield, permitting the passage of the sucker rod into positionin the opening-ll. However, after the'sucker rod has reached such position, the tendency of the jaws will j be to hold the same in position in the opening 11 and on the seat 48, as any engagement of the rod withthe'legs 26 of the jaws 24 will tend to swing the same into engagement with each other, the faces 51 of said jaws thus forming a part of the rod receiving socket and acting as stop members to prevent elevator. It will also be obvious that a downward movement of the handle 42 will cause the actuating member 39 to swing on disengagement of the rod from the its pivotso as to cause the arm .38 thereof I tomove the. pins 3'! lengthwise in the openings 36 and swing the jaws around to the position shown in Fig. 5, when the passage 14 will be opened to permit the elevator to be removed from the rod.
